 Larry Wayne Stokes, the appellant, was convicted in the Circuit Court of Williamson County of rape of a child, in violation of Tenn. Code Ann. § 39-13-522 (Supp. 1995). He currently serves a fifteen-year sentence in the Department of Correction.

We accepted the State’s application for review in this cause in order to determine the validity of an indictment which charged aggravated rape.1 The Court of Criminal Appeals held the indictment void and the subsequent conviction invalid because the language of the indictment failed to allege a culpable mental state.

We granted the defendant’s application for permission to appeal in order to determine whether the trial court abused its discretion1 in admitting testimony concerning the results of a certain method of DNA analysis. While we have previously considered the admission of the results of DNA analysis using the “restriction fragment length polymorphism” (RFLP) method, we address for the first time the admission of testimony regarding DNA analysis using the “polymerase chain reaction” (PCR) method. PCR is to be distinguished from RFLP, the method more statistically precise and firmly established in both the scientific and legal community. After a jury-out hearing, the trial court admitted expert testimony about the results of the PCR analysis performed on the defendant’s clothing, and the Court of Criminal Appeals upheld the trial court’s determination.
